Believe it or not, we're already late in the game, and we do know enough about this unsub to know that if he feels like we're closing in on him at all, he will kill Billie to avoid detection.
Em creieu o no, em avançat en el joc. i coneixem molt mes de l'UNSUB per a saber .. que si es sent acorralat matarà a ne'n Billie per a no ser descobert.
